Folks, please correct me if i'm wrong. From the reading I've done here, it appears to me that the Amazings Platinum are a 6.5 Ohms speaker correct? My amps allow me to choose 2, 4 or 8 ohms. Is this a matter of what sounds best to me or is there hard and fast rule learned from experience to use a particular tap?

They are nominal 8 ohm speakers. Use either the 8 or 4, whatever sounds best, but not 2.

Political Correctness...defined

A doctrine fostered by a delusional, illogical minority and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a turd by the clean end.

In a recent press conference, President Obama remarked, "If I had a city, it would look just like Detroit."

Or better yet, power them with a pair of silver 9t blocks and don't worry about ohms ever again. F1 is correct in saying they are rated nominal 8 ohm, the 6.5 figure comes from the total of the woofer and ribbon resistance. The woofers are 4 ohm and the ribbons 2.5-3 ohm.

How long a minute is, depends on what side of the bathroom door you're on.

Skip, if my 501's don't have enough grunt to drive these, the Amazings won't be around long! They are measured at 720w at 8 ohms and 1000 at 4 with 100 amps. I know a guy who ran his Silvers off a McIntosh 402 and they did have to work harder (heat) than driving his ML.
